How to handle dynamically created row values when get upadted "please help"

Question

Hi,
In my application I have requirement to display the data for specific date when user clicks on viewData. (it shows the entries for that specific days . There may be number of entries). For showing this I have created Value Object and I am setting all the entries for particular selection date to value object and (simply one day entry indicates one instance of my VO if there are 10 entries then I am creating 10 instances of VO and passing this to the actionfor)
On my JSP page I am displaying that data by using <logic:iterate>
<logic:iterate id=�myid� name =�nameofform� property =�Listproperty�>
<tr>
<td><input type=�text� property=�abc� value=<bean:write name=�myid� property=�propertyinVO�></td>
// and same for other other values as well
�.
</logic:itearte>
Now I have requirement that if user edit these entries and click on SAVEDATA the updated values should go to the DB.
As I don�t have property mapped separately I am not able to take updated values of those as they are getting dynamically generated
Is there is any way by which I can get these updated values.
I am in badly need of that . Urgent help will highly appreciated.
Thanks
Sheena

Hi, first off, no need to determine what has been checked or not. If the checkbox is checked, on the post, the value will be submitted as part of the request. If the checkbox is not checked, it will not be submitted (it's value will be null). Depending on what you need, I have approached this a number of different ways. One way is to name all checkboxes the same name. If you need to distinguish between two rows in the form, then in the value field for the checkbox, use some type of distinguishing factor, for example,
<input type=checkbox name=chkName value="1:abc">
<input type=checkbox name=chkName value="1:def">
Now, you only have to make one call on the Servlet/JSP receiving the form post, request.getParameterValues("chkName") which will return an array of the non-null Strings that were checked.
